英语翻译
Sitting on a chair all day in school can make anyone want to move around.So,more and more teachers are letting students have a ball.By sitting on exercise balls instead of chairs,teachers find students' posture (姿势) and attention improve.
Dottie Pownall,a fifth-grade teacher in West Virginia,USA,has been using balls as chairs since December 2008."The students love them",she says.Pownall took a survey of her students.She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning.
The teacher,Pisa Witt,felt so strongly about the use of balls as chairs,she started Witt Fitt.This company encourages the use of the balls.And the company educates not only teachers but also students on how to use them."Our products are used in 24 states,three provinces in Canada,Puert o Rico ('波多黎各) and Japan," says Witt."Research shows that sitting on the balls makes them sit up straighter.You can slouch (低头垂肩地坐) on a ball," says Witt,"but it feels awful." Because the students are moving,their blood (血液) increases.That carries more oxygen (氧气 to the brain (大脑),so the kids have more energy and can focus longer.
"Furthermore,they're fun." says Pownali.

在学校坐一天的椅子,每个人都会想活动一下.因此,越来越多的教师让学生们有个球.用健身球代替座椅后,教师发现学生的坐姿和注意力都得到了改善.Dottie Pownall,美国西弗吉利亚州一个五年级教师,从2008年12月起,就开始用球来做椅子了.“学生很喜欢它.”她说.Pownall对她的学生做了个调查,她发现有80%的人认为坐在球上能帮他们更加集中学习注意力.教师Pisa Witt感觉以球代椅非常有用,于是她选择了Witt Fitt.这家公司鼓励使用健身球,而且它不仅教教师们怎么使用,也教学生.“我们的产品遍及国内的24州,加拿大的3个省,还远销波多黎各和日本.”Witt公司称.“研究显示,坐在球上,能让人坐的更直.如果你低头垂肩地坐,会感觉很糟糕.”Witt说.因为学生在动的时候,血流量会增加.这就给大脑带来了更多的氧气,因此,孩子们就会更有精力,也能保持注意力更长时间.“还有就是,它们很好玩.”Pownali说.
